Style Lab Control Hair Spray

These describe what an ingredient is, not whether it is a problem. The stance marks above are the ratings; these are not.

• commonly dryingAlcohol Denat

  • Alcohol Denat: Denatured ethanol: a fast-evaporating solvent that thins a formula and leaves a dry finish. International Chemical Safety Card ICSC 0044, Ethanol (anhydrous), prepared by an international group of experts for the ILO and WHO: "The substance defats the skin, which may cause dryness or cracking." WHO Guidelines on Hand Hygiene in Health Care (2009) records depletion of the skin lipid barrier by lipid-dissolving alcohols, and also that "the lipid-dissolving effect of alcohols is inversely related to their concentration". Both describe stronger exposures than a cosmetic formula.

• fragrance materialCitral, Butylphenyl Methylpropional, Citronellol

  • Citral: A lemon-scented fragrance component named separately on the label; the one name covers three related substances. EU Regulation (EC) 1223/2009, Annex III entry 70: a fragrance substance whose presence must be indicated in the list of ingredients above 0,001% in leave-on and 0,01% in rinse-off products, because of established contact-allergy risk. As replaced by Commission Regulation (EU) 2026/909 of 27 April 2026, the entry is a GROUPED one covering citral, geranial and neral, declared collectively as "Citral", with per-product-type caps from 0,032% in deodorant to 1,2% in rinse-off and leave-on hair products. Its three substances carry two different sell-through dates: products not complying may not be placed on the Union market from 1 January 2027 in every case, and may not be made available from 1 July 2028 for citral, footnote (**), or from 1 August 2028 for geranial and neral, footnote (***). In the consolidated text those two footnotes are renumbered (46) and (47); both are worded "these substances", where the footnotes that attach to a single named substance say "that substance".
  • Butylphenyl Methylpropional: A lily-of-the-valley fragrance component the EU no longer permits in cosmetics. It was a declarable fragrance allergen at Annex III entry 83 of EU Regulation (EC) 1223/2009. Commission Regulation (EU) 2021/1902 deleted that entry and moved it to Annex II entry 1666 (2-(4-tert-butylbenzyl) propionaldehyde, CAS 80-54-6), prohibiting it in cosmetic products from 1 March 2022.
  • Citronellol: A rose-and-citrus fragrance component named separately on the label. EU Regulation (EC) 1223/2009, Annex III entry 86: a fragrance substance whose presence must be indicated in the list of ingredients above 0,001% in leave-on and 0,01% in rinse-off products, because of established contact-allergy risk.

• undeclared fragrance blendFragrance/Parfum

  • Fragrance/Parfum: A blend the label does not itemize, so what is in it cannot be read from the ingredient list. EU Regulation (EC) 1223/2009 permits the collective term "parfum"; the SCCS Opinion on Fragrance Allergens (SCCS/1459/11) reviews the contact-allergy evidence for the substances it can contain.

• humectantPanthenol

  • Panthenol: A provitamin B5 humectant used in products aimed at irritated and healing skin. On the humectant half: Ferreira VTP, Silva GC, Martin AA, Maia Campos PMBG, "Topical dexpanthenol effects on physiological parameters of the stratum corneum by Confocal Raman Microspectroscopy", Skin Res Technol 2023;29(9):e13317, DOI 10.1111/srt.13317, PMID 37753694, PMCID PMC10504581, open access, Introduction: "As a humectant, it has been shown to retain water more efficiently than other humectants during the last stages of dehydration..." On the soothing half, which that paper does NOT support: Cho YS, Kim HO, Woo SM, Lee DH, "Use of Dexpanthenol for Atopic Dermatitis—Benefits and Recommendations Based on Current Evidence", J Clin Med 2022;11(14):3943, DOI 10.3390/jcm11143943, PMID 35887707, open access, section 3.5: "To facilitate wound healing, dexpanthenol reduces inflammation, and promotes cell proliferation and epithelial remodeling."
